To all whom it may concern:

Be it known that I, THOMAS V. SKELLY,

vcitizen of the United States of America, and

aresident of Chica o, in the county-of Cook and State of Illinois, `have invented certain new and useful Improvements in Phonogra h- Record Holders, of. which the following 1s .a

specication.

The main objectsofithis invention areto provide an improved holder for the record cylinders of phonographs and other devices for recording and re roducingvibrations to :provide a holder'wh1ch will permit the record to be freelyv handled Without touching the recording surface, and which will'serve as a tprotector for the record when it is removed i om the machine; .to provide a holder of 'this class'ffon which a record may' be permanently mounted and which may be readily slipped upon the record-supporting mandrel of t e machine and will then serve as adrum for supporting the record in. the machine; andto provide a holder which will permit the record to freely contract or expand `through vtem erature changes without danger of brea ageeither when there'cord is on the machine or when it ,is .removed therefrom;v

thus avoidingthe cause of most of the break age off'phonogra h records.v Phono aph drum or from vaccidental blows during Athe.

records are usual y .broken through eing forced too tightly upon' the su porting drum, or from contraction when chil ed while on the handling of.' 'the records. These objects are 'accomplished by the device shown in the yaccompanying drawings, in which lFigurel is a longitudinal section of a Ipho/-y nograph record holder constructed according 1 to this 'inventionL'andshowin a cylindrical record in"` 1os'ition .thereon4 4ig. 2 is trans-' verse s ectron'of thesa'me on the line' 2 -2 of n theconstructi'on shown inthe drawings,

. the' shaft 3' represents the'mandrel o'fa pho' 245 nograph upon which the record cylinders are bearings at theleft oflifig. `1,fleaving the endV mountedf This mandrel is mounted in long 4 free and unsupported@ 'The bearing for Lthe shaft.- 3 isnot shown'in the drawing. vThe recori-holder com rises a sleeve which #fits the 'shaft 3 and w` ich is provided with heads 6 and7. each'having-therein a conical cylindrical record 9.( Each head has an inner conical coreilOivvhieh serves toro'ughly' c en. a te? ,the M014;- tliegitrue centering the rec-:'-

ord Vbeing however accomplished bythe engagement of the conical endsl of the record with the concave conical seats 'cf the heads'.

When the record is centered; .ithef'conical cores are free from'theinner hery of the record so as to permit thesame to eely contract without breakage; j- The headV 6 is preferably rigidly mounted on one 'end of the sleeve 5 and the conicalicore 10 ofthe head 6 is hollow and extends a` considerable dis Vtance inward ofthe record-S4 so'as to permit the supporting bearing (notrshown) to extend inward' of the record andgivejfirmsupport to the shaft'at' peint near the'middle of the record. v e The sleeve 5 is threaded at the end oppossite the head 6 andhas a nut. 11 mounted thereon. The headk 7 is slidable longitudinally offthe sleeve and is normally urged toward thehead 6 by means of a `spring 12 bearing. between the nut l1 and thehead 7. The end 4 of the shaft 3 is 'preferably rounded or tapered so as to permit the holder to be easily slipped endwise upon they shaft, and the shaft is provided with a shoulder 13 sie against which the end of the sleevey 5 bears'" when the sleeve is in its .normal 'position upon the shaft. The sleeve 5 is prevented` from rotating relatively of the shaft "by means of'a spring tongue 1d which is seated in a groove in theshaft 3 and bears outward so as to engage the sleeve 5. The sleeve 5 may be provided with a scat for the spring 14 so as to avoid any possibility'of relative rotatiorpof ythe record and supporting man-l drel while in operation.

" head 7,5 and spring 12 are removed fromthe sleeve and the'record is then slipped over the sameinto engagementwith the seat 8 of the head 6; The head -7 is then placed upon the' The extreme outer IOO sleeve in engagement with the other end of the'record, and the spring 'and nut are replaced, the nut being screwed inward until the s ring 12 exerts a pressure upon the head 7. he nut and s ring now serve as a handle forhandling t e record. By means .of

this handle, the record -holder may be slipped u onor. removed from the shaft 3 ofthe mac lne. 1A plurality 'of these-'record-holders with their/records mounted upon-them in the manner described, ma be stored in a cabinet protecting the record against damage .through contact with a supporting surface or the record maybe laid upon its'xsidewhen the peripheries 15 will protect -the recording surface from contact with the supporting surface. In commercial'us'e, where the records fre uently shaved off', a record may be left in its. older both while in use and whilebeing shaved, and .when it has become .worn out, itl

may be replaced by another.

Expansion of the record in a longitudinal direction is allowed througli'yielding of the' spring 12; and expansion in a transverse direction is also permitted since the conical seats of the heads accommodate themselves to changes in diameter of the conical ends of the record c linder through a llongitudinal yielding of t e spring-12. The heads protect the recording surface from contact with flat surfaces upon. which the holder is laid and also protect its edges from shocks or blows'.

What I claim as -my invention and desire to secure by Letters Patent is 1.'.A record-holder comprising a shaft, a pair of heads mounted thereon and adapted to engage opposite ends of a tubular record and support the same concentrieally'of said shaft, one of saidheads being slidable on the shaft, ashoulder on said shaft adjustable longitudinally thereof, and a springbearing between said shoulder and said slidable head and normally urging said slidable head to.

ward the other for clamping the record be. tween said heads.
